Abstract
According to some embodiments, a method performed by a wireless device for indicating an uplink performance metric in a beam sweep report comprises determining a downlink channel quality associated with each beam of a plurality of downlink beams, determining uplink performance metric associated with each beam of the plurality of downlink beams, selecting a subset of the plurality of downlink beams for reporting in abeam sweep report; and transmitting a beam sweep report to a network node based on the selected subset of downlink beams. The beam sweep report includes the uplink performance metric associated with each downlink beam in the subset of downlink beams.

A method performed by a wireless device for indicating an uplink performance metric in a beam sweep report, the method comprising:
- determining a downlink channel quality associated with each beam of a plurality of downlink beams;
- determining uplink performance metric associated with each beam of the plurality of downlink beams, wherein the uplink performance metric is based on a maximum available uplink output power (MAUOP), wherein the MAUOP is based on both an available power amplifier (PA) output power for the beam and a reduced maximum output power (P-MPR) for the beam, wherein the available PA output power for the beam is less than a maximum output power for the beam;
- selecting a subset of the plurality of downlink beams for reporting in a beam sweep report;
- and
- transmitting a beam sweep report to a network node based on the selected subset of downlink beams, wherein the beam sweep report includes the uplink performance metric associated with each downlink beam in the subset of downlink beams.
A wireless device operable to indicate an uplink performance metric in a beam sweep report, the wireless device comprising processing circuitry operable to:
- determine a downlink channel quality associated with each beam of a plurality of downlink beams;
- determine uplink performance metric associated with each beam of the plurality of downlink beams, wherein the uplink performance metric is based on a maximum available uplink output power (MAUOP), wherein the MAUOP is based on both an available power amplifier (PA) output power for the beam and a reduced maximum output power (P-MPR) for the beam, wherein the available PA output power for the beam is less than a maximum output power for the beam;
- select a subset of the plurality of downlink beams for reporting in a beam sweep report;
- and
- transmit a beam sweep report to a network node based on the selected subset of downlink beams, wherein the beam sweep report includes the uplink performance metric associated with each downlink beam in the subset of downlink beams.
